HOISTING- AND TIL'IING DEVICE.

To all whom it may concern:

Be itknown that we, JOHN H. BURR and FRANK G- BURR, citizens of theUnited in the county of Cherry and State of Nebraska, have invented anew and useful Hoistingand Tilting Device, of which the following is aspecification.

This-invention has reference to a hoisting and tilting device, adaptedparticularly for use in elevating and tilting over motor vehicles forfacilitating access to the bottom thereof to makerepairs andadjustments.

The object is to provide a portable, simply constructed device which islight in Weight,

which may be manufactured and produced upon the market at relativelysmall cost, and

' a device which is compact and may be easily handled in relativelysmall space.

Another object of this invention is to provide a frame upon which themotor vehicle "may be driven, a hand operated means for lifting uponeside of the frame and tilting the vehicle over toward one side, thehand operated means embodying certain constructions whlch hold the framefor limited movement to prevent overturmng and damage to the vehicle andto insure the positive return of the vehicle carrying frame even thoughshould the same be disposed with its lower edge Within the verticalplane of its upper edge.

The inventionalso embraces certain other objects and advantages whlchwill hereinafter be pointed out and understood from the followingdetailed description of the present preferred embodiment of thisinvention, the same being illustrated in the stantially forty-fivedegrees.

the vehicle receiving frame in position.

Fig. 5 is an end view of the device, showing a slight modification inthe raising and lowering means.

Referring to these drawings, the device comprises a frame portion orbody part made up of a pair of spaced apart rails 10 of channel ironconstruction and with preferably the fianges upturned to form a guideway within each rail 10. The rails 10 are transversely disposed withrespect to the lonaXis of the device and are suitably heldin spacedapart relation such as partly tilted .by'ineans of a pair of crossed tierods 11.

The tie rods 11 are secured at opposite ends by bolts 12 to the rails 10at one side of the machine.

The rails 10 are each provided with a standard or post13 which is seatedin a socket 1 1 at its lower end and clamped to the rail 10 by bolts orthe like. The standards are arranged near the ends of the rails 10 andat one side of the device. Braces 15 are secured at their lower ends tothe rails 10 by preferably the outer bolts 1:2- which are also employedfor holding the tie rods 11 in place. The upper ends of the braces 15are secured to the standards 13 near the upper ends of the latter bybolts 16.

Normally resting across the rails 10 is avehicle receiving frame formedof a pair of side bars 17 of angle iron construction and provided withrelatively deep base flanges upon which the wheels of the vehicle areadapted toroll. The bars 17 are held apart by pairs of crossed bracerods 18 secured by rivets 19 or the like to the bars '17 near the endsof the latter. The bars 17 are further reinforced by straps 20 which aresecured at opposite ends to theundersides of the base flanges of thebars by the said rivets or bolts 19. The inner ends of the straps, orthe ends adjacent the standards 13, are longitudinally slit to form apair of tongues on each strap 20 which are twisted 1ntoa plane at rightangles to that of the strap 20. These tongues or cars 21 have pivotedbetween them the lower end of a flat l1nk 2 1 The yoke 23 is preferablyare closed by transverse rollers. 27. having grooved peripheriesconforming in contour to the cylindrical exterior surfaces of thestandards, the rollers 27 being supported upon transverse pins or thelike in the free ends of the yoke s. An'elevating cable 28 is attachedat one end to the upper end of each 7 bar 24 and passes over a pulley 29seated in theupper end of each standard 13. the cables 28' passing downat the inner sides of the standards 13 and being secured to alongitudinal shaft 30 which is journaled near its opposite ends in thebraces 15 and at a suitable height.

The shaft 30 has a crank arm 31 on its end adapted to be turned by handfor rotating the shaft 30 and winding the cable 28 thereon The cableQSis wound upon the shaft 30 preferably between the posts 13,

and a second cable 32 is wound upon each end of the shaft 30 beyond theposts 13. The cables 32 are connected at their free ends to steadyingarms which are pivotally mounted upon the inner side of the'vehiclereceiving frame. The ends oft-he arms adjacent the frame are pivoted onpins 34C which pass through the lower ends of brackets 35 securedvertically upon the inner side of said frame, the brackets 35 risingabove the vehicle supporting frame and having secured thereto tensionsprings 36 which are fastened at their other ends to the rear eX-tremities of the arms 33. The springs 36 normally urge the arms 33upward and thus maintain the cables 32 taut at all times. The innerendsof the arms 33 project beyond the brackets 35 and form shoulders orsupports 37 adapted to bear against the underside of thevehiclereceiving frame to limit the downward swinging of the arms 33.The bars 17 are bent down at opposite ends to form inclined ways adaptedto elevate the 7 wheels of the vehicle and to admit thegradualdepositing of the vehiclefrom and upon the ground with referenceto the vehicle receivingframe. i r

The outer side of the vehicle receiving frame is provided with a, pairof rollers38 mounted in brackets 39 which are riveted orotherwisesecured to the outer bar 1?; the wheels 38 being arranged"totravel in the rails :10 and to support the frameaird the ve-hiclethereon when the innerside of the frame is elevated. The brackets 39 aretilted downward at aslight angle to position the rollers 38 in contactwith the rails 10 at practically all times.

In Fig. 5 the modification embraces a cable ll) which is trained overthepulley 29 and which extends downwardly and out- \vardly over the vehiclereceiving frame and is attached to the outer bar 17 thereof at ll. Thetension cable a2 is connected to the outer bar 17, passes through apulley block i3 mounted on the outer end of the adjacent rail-1.0, andextends inwardly along. the rail to a pulley l i mounted on the innerend of the rail 10, and from the latter pulley to the shaft 30 beyondthe post 13. This construction prevails at each endof the device, and inthis instance. the posts 13 must be spaced apart a distance greater thanthe length of the vehicle placed upon the elevating frame so that thecables 40 will clear the ends of the vehicle.

The inner side of the vehicle supporting frame has an car 45 oppositeeach post 13 and which is pivoted by a pin 46 to a collar t: whichsurrounds. the lower end of each post 13 and serves as an anchor for theinner side of the frame. Vllhen this modified form is used the rails10.:must extend rearwardly of the posts 13 a distance beyond the centerof gravity of theveliicle mounted on the tilt ing frame. 7

When the modified structure is used, a vehicle is. run up upon thetilting frame with the wheels supported on the bars or rails 17. Thevehicle has its wheels fastened to the bar 17 by a strap 48 or the likesuch as shown in Fig. The operator now turns the crank handle 31 androtatesthe shaft-30 in a direction towind the cable 40 thereon .thevehicle intilted position. When it is desired to lower the vehicle theshaft 30 is The i turned in an opposite direction towind the cable 4:2thereon and to unwind the'cableflO and thus. draw the tilting frame downinto position upon thetracks 10. V

In the preferred form when the shaft 30 is turned in one direction thecable 28 lifts theyoke upon the standard 13' and thus draws the innerend of the tilting frameiup and holds said end. ofthe .tiltingframepractical-ly in the same vertical plane throughout its movement. Theouter end of the tilting frame is thus drawn inwardly toward the post 13andthe roller 38reduces frictional contact between.the-frame andthat-rack 10, and takes up the niaj or portion-of. the veight of thevehicle. Inthisinstance the strap 48 is secured about the innerbar 17;and th ead-V V =jace nt wheels of the vehicle; Ofcourse this "oppositeends of the device, and the posts 13 may be spaced apart any suitabledistance to provide a'strong and stable device.

As the tiltingframeis raised, the tension cable 82 is unwound from theshaft and the inequalities in the relative movements of the and thetilting frame aretaken up swinging ofthe arms 38 downward as the frameis raised.

lVhen it is desired to lower the vehicle, it is only necessary toiturnthe shaft in an opposite direction to wind the cable 32 thereon and drawthe cable and the arm down until the shoulder 37 of the adjacent armengages the underside of the tilting frame; The arms 33 are utilizedchiefly in preventing the vehicle from turning sud denly over on itsside, and for throwing out the free end of the tilting frame from theposts should the tilting frame be raised sufiiciently to lie in averticalplane. The return of the tilting frame to normal position isthus positively assured as the cable 32 draws the frameback to lowered"position and the cable'28 gradually takes up the weight of the vehicle.i

it is of course understood that various changes and modifications may bemade in thedetails of construction and design of the above specificallydescribed embodiment of this invention without departing fromthe spiritthereof, such changes and-modifiations being restricted only by thescope of the following claims.
